PYREX® Square Glass Media Storage Bottles, GL32 Screw Cap

Engineered for durability and efficiency, our PYREX® Square Glass Media Storage Bottles are the ideal choice for your laboratory's storage and mixing needs. Manufactured from high-quality PYREX® borosilicate glass, these bottles offer remarkable chemical and thermal resistance, ensuring reliable performance in various conditions.

Designed with a square shape, these bottles maximize space efficiency, utilizing 13-20% less shelf or autoclave space compared to traditional round bottles. The thoughtful design features white enamel graduations for easy measurement, a large marking spot for labeling, and a molded glass ridge indicating full capacity.

Key Features:

• Includes a linerless, one-piece autoclavable orange GL32 threaded polypropylene plug seal cap.
• Drip-free pouring ring for mess-free dispensing.
• A wide selection of optional caps available, including:
• Polypropylene colored caps for easy sorting and identification.
• Vented membrane cap with 0.22 µm PTFE hydrophobic membrane for optimal filtration.
• PBT (polybutylene terephthalate) solid caps and ETFE pouring rings for effective dry heat sterilization (up to 180°C).
• PBT caps with silicone septa for syringe sampling or reagent introduction.

Important Cautions: These square bottles are not suitable for use with bottle top filter units or any applications involving vacuum pressure due to potential breakage. After autoclaving, avoid tightening caps immediately. The resulting vacuum from cooling may lead to breakage.

Storage Consideration: Performance under freezing conditions may vary based on temperature and bottle contents. Conducting a trial run under actual storage conditions is strongly recommended to ensure suitability of the bottles for frozen storage.
